     • When an antenna is used for transmitting a signal, an electrical current oscillates within the antenna. The oscillating current generates an electromagnetic wave that propagates through the air or other media. The antenna’s shape and size determine the radiation pattern and directivity, which affects signal transmission efficiency.

   What does an antenna do?

   • An antenna is a conversion device or transducer between a guided wave and a free space wave. Its basic function is totransmit and receive radio waves: when transmitting, it converts high-frequency currents into electromagnetic waves; when it receives, it converts electric waves into high-frequency currents.

   How does an antenna radiate radio waves?

   • Antenna radiating radio waves: The transmitter applies an alternating current (red arrows) to the rods, which charges them alternately positive and negative, emitting loops of electric field. The arrows of the loops get reversed each time the current changes polarity.

   How does a half wave dipole antenna work?

   • Half-wave dipole antenna receiving a radio wave: The electric field (E) of the incoming wave pushes the electrons in the rods back and forth, and oscillating currents (black arrows) flow through the receiver.
